🚧 Breaking Changes

v2.0.0

• 🚚 rename requestPermission() method to requestOverlayPermission().
• 🚚 rename hasPermission() method to hasOverlayPermission().
• 🚚 rename options parameter in startBubble() method to bubbleOptions.
• ✨ add notificationOptions parameter to startBubble() method and move the notification options from bubbleOptions to the new notificationOptions.
• 🛂 starting from Android 13 (Tiramisu), the service notification will not be shown unless the POST_NOTIFICATIONS permission is granted at the runtime, refer to the Service Notification section for details.

v1.0.0

• 🚚 rename onBubbleTap() callback to onTap() in startBubble() method.
• ✨ convert the values of startLocationX and startLocationY to be in density-independent pixels (dp) instead of pixels (px) as per Flutter convention.

🔧 Setup

Set the minimum SDK version to 21 or higher in your android/app/build.gradle file:

android {
    defaultConfig {
        ...
        minSdkVersion 21 // Set this to 21 or higher
        ...
    }
}

The plugin uses these two permissions but you don't need to add them to your AndroidManifest.xml file because the plugin will add them automatically:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

💻 Usage

Import the package:

import 'package:dash_bubble/dash_bubble.dart';

Use the singleton instance of DashBubble to access all the available methods, for example:

DashBubble.instance.requestPermission()
DashBubble.instance.startBubble()

🔔 Service Notification

The service notification is a non-dismissible notification that is shown when the bubble is running to keep the service alive.

The notification is shown automatically when the bubble is started and hidden automatically when the bubble is stopped.

Currently, their is no way to disable the notification.

Note: Starting from Android 13 (Tiramisu), the POST_NOTIFICATIONS permission must be granted to show the notification, however, you don't need to add the permission to the AndroidManifest.xml file because it is already added by the plugin, but you need to request it at the runtime, otherwise the notification will not be shown.

This permission can be requested by calling requestPostNotificationsPermission() method and can be checked by calling hasPostNotificationsPermission() method.

If the permission is not granted, the notification will not be shown but the bubble will still work normally.

Customization Options

The service notification can be optionally customized by passing a notificationOptions parameter to the startBubble() method.

Note: All the options are optional and you can pass only the options you want to customize. Here is a list of the available options in the notificationOptions parameter:

Option	Description	Default	Notes
id	The id of the service notification	101	-
title	The title of the service notification	null	If not provided, the title will be the app name
body	The body of the service notification	null	If not provided, there will be no notification body
icon	The icon of the service notification	null	The icon is set as an image file placed inside android\app\src\main\res\drawable\ and the value of the parameter should be the the file name without the extension If not provided, the icon will be the plugin icon
channelId	The channel id of the service notification	bubble_notification	-

• ❌ Ability to pass a Widget as the bubbleIcon and closeIcon 💪🏻
• ❌ Implement the ExpandableView feature in the original library ⚡
• ✅ Implement the the rest of the available callbacks in the original library onMove(x,y), onUp(x,y), and onDown(x,y) 🔗
